You Learned Rails...Now What?
If you have been using Rails for 6 months or more but you still feel like you could be doing a lot better...
...and if you are not really happy with your code...
...then this could be the most important message you will ever read.
my name is Jesus Castello & I have using Ruby for over 6 years & teaching it for about 2 years.
In my experience, most of my students have this uneasy feeling because they haven't been taught Ruby fully.
Most courses & books just focus on the surface details.
That's a bit of a problem when it comes to writing better Ruby code & being able to do projects outside of Rails.
That's why I invested over 100 hours of my time to put together a resource for you...
A resource which:
- Helps you build a solid foundation of Ruby skills
- Bridges the gap between the fundamentals & more advanced concepts
- Shows you the tools, ideas and examples you need to understand things better
The resource I'm talking about is Ruby Deep Dive, the book for serious Ruby developers.
It's Not Only a Book, It's a Complete Package
Ruby Deep Dive is a complete package to help you build a solid Ruby foundation, bridging the gap between the fundamentals & more advanced concepts.
This is what is included:
- A 160-page PDF eBook
